Abstract
ABSTRACT Sialolithiasis is a pathological process that affects the major salivary glands. It consists of calcifications that obstruct the parenchyma of the gland and / or the lumen of the ducts. The 37 years old female patient, VBB, leucoderma, attended the stomatology service with a complaint of swelling in the floor of mouth, which she noticed 10 years ago. The clinical and radiographic exams indicated a diagnosis of multiple sialolithiasis in the left submandibular gland duct. Surgical intervention was indicated in this case. Amongst all sialolithiasis cases, 80% affect the submandibular glands. Of these, 70% are isolated sialoliths. Only 5% of cases present more than 3 calcifications. This study aims to report the diagnosis and treatment of a rare case of multiple sialoliths located in the duct of the submandibular gland, which were surgically removed via intraoral access.
Highlights
Sialolithiasis is a lesion of the salivary glands consisting of calcifications located in the glandular parenchyma or their associated ductal systems [1]
Intraductal sialoliths appear more commonly than those found in the glandular parenchyma [2]
VBB, a female patient, aged 37, leucoderma, Sialolithiasis accounts for approximately 30% of attended the Stomatology Clinic of the Department of salivary changes [2]
Summary
Sialolithiasis is a lesion of the salivary glands consisting of calcifications located in the glandular parenchyma or their associated ductal systems [1]. Intraductal sialoliths appear more commonly than those found in the glandular parenchyma [2]. Postmortem studies have shown that calculi are present in approximately 1.2% of the population and account for approximately 66% of all benign intraductal obstructions [1]. A sialolith develops from a nucleus of mineralization around bacterial niches, debris, cell remnants, or foreign bodies [4,5]. Its etiology may be related to morpho-anatomical factors, salivary composition or its stasis. Increased salivary pH, infections, inflammations, ductal or glandular trauma are factors that may predispose an individual to sialolithiasis [2,5]
